Everyone knows Merino is great at keeping you warm when it’s cold, but did you know our exclusive ‘Summerino' range is just as effective at keeping you cool and comfortable when it’s warm? The natural breathability and temperature regulating properties of our MicroMerino® fabrics help keep you insulated against whatever Mother Nature can throw at you.

Our 'Summerino' range of superfine, soft, lightweight, moisture wicking and odour-resistant gear delivers UV protection from the sun and a revolution in comfort all year round.

Find out the 10 reasons you need our Summerino Range this summer.

We compare our Summer Merino range to the insulation in your house or even a woollen under-blanket on your bed. You keep it on all year round; in winter keeps you warm, while in summer it keeps you cool. It’s basically one of nature’s many little miracles. Which is why we developed our 'Summerino' range - Merino that still delivers a layer warmth when it’s cold outside, but is made light enough to be super comfortable in the heat.

Made with ultra-light 150gsm 100% superfine Australia Merino for breathable, weightless, silkly smooth feel.



Fabric Guide

While Merino is an amazing natural fibre, not all Merino fabrics are created equal. At ioMerino, we make our own fabrics, using only the best quality fibres, and to very specific specifications that make the most of the natural benefits of Merino. All of them are 'Merino rich’. No cheap blends passed off as Merino. No cheaper scratchy fibres or synthetic substitutes to save money. No unethical production. And each fabric is made for a specific purpose. So if you see something with a small amount of elastase or nylon added, you can be sure it absolutely needs to be there to enhance the natural stretch and durability. 

It took every bit of our 140 years of experience in the wool industry to perfect our fabrics, but we think you’ll agree the end result was more than worth the effort.

Ethically Made. Ethically Sourced. Perfectly Natural.
